(CNN)Johnny Manziel's turbulent time with the Cleveland Browns ended in March, and his future in the NFL is in doubt. After two years in the league and now facing an assault allegation, Manziel's NFL career could flame out almost as quickly as he rose to stardom.

A Texas grand jury has indicted Manziel on an assault charge, according to Dallas County court records. Manziel's former girlfriend Colleen Crowley says in an affidavit that the NFL quarterback restrained, hit and threatened her during an alleged assault. She says Manziel grabbed her by the hair and hit her, causing her to lose her hearing in one ear. Manziel has denied hitting Crowley.
